<；P>；PROBLEM TO BE SOLVED: To solve problems in a sowing machine to deliver and sow a seed by rotating a delivery roll holding the seed fit in a sowing groove on a rotating circumference, that the outer circumference of a delivered seed is liable to be damaged owing to large frictional resistance applied to the seed which is fit in the sowing groove in delivery by a cover covering the rotating circumference of the delivery roll and a guide plate, etc., especially when the seed has a direct sowing form covered its outer circumference with Calper(R), the seed size is increased to protrude the seed from the sowing groove beyond the outer circumferential face, get a large delivery resistance and cause damage and peel of the Calper-coated part. <；P>；SOLUTION: In the sowing machine provided with the delivery roll 2 having the delivery groove 1 on the rotating circumference for fitting the seed, to make the seed fit in each delivery groove 1 delivered and sowed with space by rotating the delivery roll 2, the delivery cover 3 made of a resilient material having resilient force to cover the groove opening of the delivery groove 1 is placed along the delivery-side rotary circumference of the delivery roll 2. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
